Elven anatomy

[Taniquetil]

There hath not been a good opinionated discussusion for a while, and I do believe I have found a topic that may begin one; so here it is.

(Yes, I realize that most answers will come from Morgoth's Ring, but I cannot find that book at any of the various surrounding libraries)

Did Elves, in fact, have pointy ears?
Did they have ten fingers or twelve?
Were there any brown-haired elves?
And (most abstractly) Could an elf be overweight? (I am fully aware of the prophesy of Mandos which states " no illness may assail you," but still...)

Come forth and speak, loremasters.....
